摘要： This disclosure describes techniques for measuring the resistance of a component with measurement circuitry that is electrically coupled to the component via one or more electrical conductors (e.g., one or more bond wires). The resistance measurement techniques of this disclosure may measure a resistance of an electrical conductor, and generate a value indicative of a resistance of a component other than the electrical conductor based on the measured resistance of the electrical conductor. The electrical conductor for which the resistance is measured may be the same as or different than one or more of the electrical conductors that the couple the measurement circuitry to the component to be measured. Using an electrical conductor resistance measurement to determine the resistance of a component may improve the accuracy of the resistance measurement for the component.

摘要： Systems and methods for adaptive distance protection are provided. An adaptive ground distance protection system may be installed in a power system to provide an accurate measurement of the apparent impedance of the transmission lines thereby ensuring reliable and stable operations of the power system. The potential of a system ground in reference to the remote earth is measured and used in calculating the apparent impedance of a transmission line. An accurate assessment of the apparent impedance of a transmission line is therefore provided and reduces the risk of misoperation of relays. Existing protection systems of a power system may be augmented, for example, via a retrofitting process, to enhance reliability of the power system, reduce costs, reduce customer service interruption, and expand opportunities for deployment.

摘要： A method of accurately measuring earth resistance even when the composition state of soil that affects the installation of a metering device for measuring earth resistance is unknown. The method comprises measuring a potential at a first potential electrode point, measuring a potential at a second potential electrode point, calculating a voltage slope corresponding to a change rate of potential difference, using a potential difference between the first and second potential electrode points, and setting a potential point according to voltage slope characteristics and measuring earth resistance. A measurement approximating an accurate value of earth resistance can be performed even when soil composition characteristics are unknown at a site.
